I read a story about a guy who climbed down after his afternoon hunt and on his way out he decided to go check on some fresh scrapes he was seeing. Well he turned his light of as he entered the area and worked his way to the scrape he, then bent down real low so he could see/feel if it had been reworked. He then heard the unmistakeable sound of an alluminum arrows sliding across an arrow rest as it was being drawn, of course he jumped back and yelled and needless to say both of them were scared sh!tless.

ALWAYS use a light, it could very well save your life.
